What Was Happening When?

This is an interesting site where you can plug in a date and find out what else was happening on that date and around that same time.

For instance, I know now that on the date I was born, gasoline cost $0.31 a gallon and a first class stamp was $0.04. When Wendy popped out, gas was $0.35 and stamps were $0.06. By the time The Boy was born, gasoline was up to $1.20 a gallon and a stamp cost $0.22.

Monopoly was deemed the "hot new toy" the year my mother was born while Nintendo earned that designation the year The Boy arrived.

As I typed this fascinating information, I began to wonder of it's relevance. And why I find it interesting. I'm still wondering.
